You need to use ScrollPosition.

Something like:

B4X:

Sub SV_ScrollChanged(Position As Int)
   If sv.Height + Position >= sv.Panel.Height Then
      Log("bottom")
   End If
End Sub

Hi Ohanian,

Curiosity killed the mouse (but only the mouse!)..

May I ask why would you want to be notified when you are already at the bottom of it and the item is highlighted?

@Erel: is he event "ScrollChanged" fired as the user scrolls up and down, and for each item? if correct then this is a great feature because it can be used to give the user a hint about the item before selecting it.

The ScrollChanged event is raised whenever the ScrollView scroll position changes. It is not related to any item.

Hi,
I have a large list and at the startup I only load about 100 records, when the user reaches the end on this list I'll load the second part and so on.
